Description

Technical Field

[0001] The present invention relates to the field of refrigeration technology, and in particular to a door assembly of an embedded refrigeration device and the embedded refrigeration device. Background Art

[0002] In today's society, the rapid progress of science and technology has greatly promoted the transformation of home lifestyles. Among them, built-in furniture, as a design concept that combines beauty and practicality, is favored by consumers. By cleverly integrating electrical appliances or storage space into the home environment, built-in furniture not only effectively saves space, but also significantly improves the overall coordination and aesthetics of the home. Take the built-in refrigerator as an example. This design allows the refrigerator to be seamlessly embedded in the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, although the built-in refrigerator has shown significant advantages in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in its actual use: the door is prone to interfere or collide with the side wall of the cabinet during opening, resulting in a poor user experience of the built-in refrigerator. Summary of the invention

[0003] The present invention aims to solve at least one of the technical problems existing in the related art. To this end, the present invention proposes a door assembly of a refrigeration device, which can solve the problems of interference and collision of the door assembly and improve the user experience.

[0004] The invention also provides an embedded refrigeration device.

[0005] A door assembly of an embedded refrigeration device according to an embodiment of the first aspect of the present invention includes:

[0006] The door is rotatably connected to a refrigeration box of the refrigeration device, and the refrigeration box is used to be embedded in the accommodation space formed by the installation body;

[0007] Sliding mechanism;

[0008] A door panel is connected to the box door through the sliding mechanism so as to move relative to the width direction of the box door;

[0009] The door has a critical door opening angle, and the critical door opening angle is smaller than the maximum door opening angle of the door;

[0010] During the process of the box door rotating from the closed position to the critical door opening angle, the sliding mechanism drives the door panel to move relative to the box door, and the moving distance Δs is not less than the critical safety distance corresponding to the critical door opening angle; the critical safety distance is the minimum sliding distance required for the door panel to not interfere with the outside world during the process of the box door rotating from the closed position to the maximum opening angle; during the process of the box door rotating from the critical door opening angle to the maximum door opening angle, the door panel is stationary relative to the box door.

[0011] According to the door assembly of the embedded refrigeration device of the embodiment of the present invention, during the process of opening the door assembly, before reaching the maximum opening angle, the door panel stops sliding relative to the cabinet door, that is, during the latter part of the door opening process, the door panel is stationary relative to the cabinet door, thereby improving the stability of the door assembly structure, making the movement of the door panel more concealed, and reducing the user's worry about the door panel falling off. In addition, since the larger the opening angle of the door assembly is, the closer it is to the user, the door panel stops sliding in advance, which can reduce the noise impact during the door opening process and improve the user experience.

[0012] According to one embodiment of the present invention, the critical safety distance is the difference between the length L2 of the door panel beyond the accommodation space and the length L1 of the door beyond the accommodation space, where L2 = y + c + d2, where L1 = y - {x - (ab) + d3 + h}, L2 - L1 = c + d2 + {x - (ab) + d3 + h}

[0014] According to one embodiment of the present invention, the door panel has a first interference position and a second interference position, the first interference position is located at the inner corner of the door opening side of the door panel, and the second interference position is located at the outer corner of the hinge side of the door panel;

[0015] The critical safety distance satisfies: before the first interference position leaves the accommodating space, there is a gap between the first interference position and the side wall of the accommodating space corresponding to it; when the second interference position leaves the accommodating space, there is a gap between the second interference position and the side wall of the accommodating space corresponding to it.

[0016] According to an embodiment of the present invention, the critical safety distance further satisfies: after the second interference position leaves the accommodating space, there is a gap between the second interference position and the panel of the installation body.

[0017] According to one embodiment of the present invention, the critical door opening angle is between 1° and 105°.

[0018] According to one embodiment of the present invention, the maximum door opening angle is between 90° and 135°.

[0019] According to one embodiment of the present invention, the sliding mechanism comprises:

[0020] A base, wherein the base is provided with a second track and a third track;

[0021] A second moving part, slidably mounted on the second track;

[0022] A third moving part, slidably mounted on the third track, the third moving part being connected to the door panel;

[0023] A connecting member, one end of which is connected to the second moving part, and the other end of which is connected to the third moving part.

[0024] According to one embodiment of the present invention, the connecting member comprises:

[0025] A first flexible cable, passing around one end of the base, with two ends respectively connected to one end of the second moving part and one end of the third moving part;

[0026] The second flexible rope is wound around the other end of the base, and two ends of the second flexible rope are respectively connected to the other end of the second moving part and the other end of the third moving part.

[0027] An embedded refrigeration device according to an embodiment of the second aspect of the present invention includes:

[0028] A refrigeration box body, adapted to be embedded in the accommodation space;

[0029] The above-mentioned double-door assembly.

[0030] A method for controlling a door assembly of an embedded refrigeration device according to a third aspect of the present invention includes:

[0031] Determine the critical safety distance of the door body assembly when rotating relative to the refrigeration box based on the size parameters of the door body assembly, wherein the refrigeration box of the refrigeration equipment is suitable for being embedded in the accommodating space formed by the mounting body, the box door of the door body assembly is suitable for being rotatably connected to the refrigeration box, the door panel of the door body assembly is movably mounted on the box door, and the door panel can move along the width direction of the box door, and the critical safety distance is the minimum sliding distance required for the door panel to not interfere with the outside world during the process of the box door rotating from the closed position to the maximum opening angle;

[0032] During the process of opening the door, it is determined that the movement distance Δs of the door panel toward the door opening side of the door reaches the critical safety distance, and the door body is controlled to stop moving relative to the door.

[0051] In today's society, the rapid progress of science and technology has greatly promoted the transformation of home lifestyles. Among them, built-in furniture, as a design concept that combines beauty and practicality, is favored by consumers. By cleverly integrating electrical appliances or storage space into the home environment, built-in furniture not only effectively saves space, but also significantly improves the overall coordination and aesthetics of the home. Take the built-in refrigerator as an example. This design allows the refrigerator to be seamlessly embedded in the cabinet, perfectly blending with the kitchen decoration style, creating a modern and harmonious living environment. However, although the built-in refrigerator has shown significant advantages in improving home aesthetics and space utilization, there is still a problem that cannot be ignored in its actual use: the door is prone to interfere or collide with the side wall of the cabinet during opening, resulting in a poor user experience of the built-in refrigerator.

[0052] Specifically, when a built-in refrigerator (referred to as refrigerator) meets the user's needs for two different types of refrigerators, namely, a purely flat and fully embedded refrigerator, the refrigerator door body (referred to as box door) will be connected to the cabinet door panel (referred to as door panel), causing the entire door body assembly to become thicker. As a result, after the refrigerator is pushed into the storage space of the cabinet, the door body assembly with the cabinet door will interfere with the cabinet during the process of opening and closing the door, relying only on the original single-axis or double-axis structural hinges of the refrigerator, resulting in an inability to open and use it normally.

[0053] Therefore, the present application proposes a door body assembly (referred to as door body assembly) that enables relative sliding between the refrigerator door and the door panel, so that in the process of opening the door body assembly, the door panel can slide toward the side where the door is opened (that is, the door opening side), so that in the process of opening the door, the hinge side still maintains the thickness of the refrigerator door itself, which is consistent with the door opening scene without a door panel; in the process of closing the door, the door panel will move toward the hinge side and return to the state before the door is opened; thereby, the embedded installation requirements of the refrigerator can be met with or without a door panel.

[0054] Among them, if the door panel and the cabinet door continue to slide relative to each other, when the door is opened at a large angle, the sliding distance of the door panel of the cabinet door is large, which will cause the user to panic and worry that the door panel will fall off, affecting the user experience. This worry is particularly obvious when the refrigerator is fully loaded or the refrigerator is tall. Based on this, the application further proposes a door body assembly of an embedded refrigeration device, which can solve the interference problem of the door panel, and when the cabinet door is opened to a certain angle, the door panel stops moving relative to the cabinet door, thereby improving the user experience.

[0055] See also Figure 1 and Figure 2 , the door body assembly includes a door 2, a sliding mechanism 4 and a door panel 9. Among them, the door 2 can be rotatably connected to the refrigeration box 1 of the refrigeration equipment, and the refrigeration box 1 is used to be embedded in the accommodating space formed by the installation body. The installation body here generally refers to the cabinet 6. Of course, the installation body can also be a wall corner, or the installation body can also refer to other components, as long as the accommodating space can be formed. The following description takes the installation body as the cabinet 6 as an example. The door panel 9 is connected to the door 2 through the sliding mechanism 4 to move in the width direction relative to the door 2. The door 2 has a critical door opening angle, which is less than the maximum door opening angle of the door 2. In the process of the door 2 rotating from the closed position to the critical door opening angle, the sliding mechanism drives the door panel 9 to move relative to the door 2. In the process of the door 2 rotating from the critical door opening angle to the maximum door opening angle, the door panel 9 is stationary relative to the door 2. Among them, in the process of the box door 2 rotating from the closed position to the critical door opening angle, the movement distance Δs of the door panel 9 needs to ensure that the door panel 9 does not interfere with the entire door opening process. Therefore, the moving distance Δs is not less than the critical safety distance; the critical safety distance is the minimum sliding distance required for the door panel 9 to not interfere with the outside world during the process of the box door 2 rotating from the closed position to the maximum opening angle.

[0056] According to the embodiment of the present application, during the opening process of the door assembly, before reaching the maximum opening angle, the door panel 9 stops sliding relative to each other, that is, during the latter part of the door opening process, the door panel 9 is stationary relative to the box door 2, thereby improving the stability of the door assembly structure, making the movement of the door panel 9 more concealed, and reducing the user's worry about the door panel 9 falling off. In addition, since the larger the opening angle of the door assembly is, the closer it is to the user, the door panel 9 stops sliding in advance, which can reduce the noise impact during the door opening process and improve the user experience.

[0057] According to an embodiment of the present application, the range of the critical safety distance may be determined in a variety of different ways.

[0058] In one embodiment, if the maximum opening angle of the door assembly is 90 degrees, then at this time, in order to meet the requirement that the door assembly does not interfere, one of the necessary conditions is that when the door 2 is opened 90 degrees, there is an assembly gap d2 between the door panel 9 and the panel of the cabinet 6, where the panel of the cabinet 6 is the second cabinet panel 602 in the figure, and of course the first cabinet panel 601 also belongs to the panel of the cabinet 6. Among them, in order to ensure that there is an assembly gap d2 between the door panel 9 and the panel of the cabinet 6 when the door 2 is opened 90 degrees, at this time, the movement distance of the door panel 9 relative to the door 2 is L2-L1=c+d2+{x-(ab)+d3+h}. Furthermore, as long as the movement distance Δs is not less than L2-L1, it can be ensured that when the door 2 is opened to 90 degrees, the door panel 9 does not interfere with the outer surface of the second cabinet panel 602. Here, the assembly gap d2 is generally greater than zero. Of course, in the extreme case, the assembly gap d2 can also be equal to zero, and then when the door 2 is opened to 90 degrees, the door panel 9 just does not contact the second cabinet panel 602.

[0059] Among them, L2=y+c+d2, L1=y-{x-(ab)+d3+h}, L2-L1=c+d2+{x-(ab)+d3+h}.

[0060] Among them, y is the width of the door 2, c is the difference in width between the door panel 9 and the door 2 (not marked in the figure, and some parameters are not marked in the figure later), d2 is the assembly gap reserved between the cabinet door and the panel of the installation body when the door 2 is opened to the maximum opening angle, x is the thickness of the door 2, a is the longitudinal wheelbase of the door 2, that is, the distance from the inner surface of the door 2 to the hinge axis 101 of the door 2 when the door 2 is closed, b is the transverse wheelbase of the door 2, that is, the distance from the end face of the hinge side of the door 2 to the hinge axis 101 of the door 2 when the door 2 is closed, d3 is the assembly gap between the door 2 and the cabinet door, and h is the thickness of the cabinet door.

[0061] According to an embodiment of the present application, when the assembly gap d3 between the box door 2 and the cabinet door is 6 mm, and the thickness h of the door panel 9 is 23 mm, the total thickness of the door body assembly is x+d3+h=x+29.

[0062] When the door panel 9 is opened to 90°, the door 2 extends beyond the edge line L1 of the cabinet 6 by y-{x-(ab)+d3+h}. When the lateral wheelbase b of the door 2 is 12.5 mm, L1=y-{x-(a-12.5)+6+23}=y-x+a+41.5.

[0063] When the door panel 9 is opened to 90°, the door panel 9 extends beyond the edge line L2 of the cabinet 6 by y+c+d2. When the width difference c between the door panel 9 and the cabinet door 2 is equal to 8 mm, and the cabinet door 2 is opened to the maximum opening angle, the reserved assembly gap d2 between the cabinet door and the panel of the installation body is 5 mm. At this time, y+c+d2=y+13.

[0064] In summary, when the door panel 9 is opened to 90°, the distance that the door panel 9 extends beyond the cabinet door 2 is L2-L1=y+13-(y-x+a+41.5)=x+a+54.5, and the units in the above formulas are all millimeters.

[0065] That is, when the cabinet door moves relative to the cabinet door 2 by a distance Δs reaching x+a+54.5, it can be realized that the cabinet door 2 and the second cabinet plate 602 do not interfere with each other during the entire process of opening the door 90°. During the door opening process, the earlier this distance is achieved, the better the user experience, that is, the sliding of the cabinet door 2 and the door plate 9 will only occur when the door is just opened. When the door angle increases later, the load and bearing feeling of the cabinet door 2 will gradually increase. At this time, the cabinet door 2 and the door plate 9 will no longer slide relative to each other, which will increase the physical sense of the refrigerator's stability.

[0066] Based on the above requirements, the embodiment of the present application uses motion simulation or formula calculation to obtain the parameters of the sliding mechanism. If the sliding mechanism is implemented by a connecting rod, the connecting rod length and initial angle can be calculated. If the sliding mechanism is implemented by gear transmission, the number of gear teeth and pressure angle can be calculated. In this way, when the refrigerator door is just opened, the cabinet door 2 and the door panel 9 slide relative to each other, and stop sliding relative to each other at a certain angle, that is, when the cabinet door 2 is fully opened, the cabinet door 2 and the door panel 9 are in a relatively static state, thereby improving the user experience.

[0067] Taking the connecting rod mechanism as an example of the sliding mechanism, let the connecting rod length be m and the initial angle be α. According to Adams motion simulation or theoretical calculation, it can be obtained that when the connecting rod length and the initial angle are a certain value, the displacement value corresponding to different door opening angles can be obtained. This is to find out the door opening angle corresponding to the above relative sliding distance value, and then find out the corresponding connecting rod length and initial angle value. Beyond this angle, the door panel 9 and the box door 2 will no longer slide relative to each other. Similarly, when closing the door, the opposite is true, that is, when the door 2 and the door panel 9 start to close, there is no relative sliding, and sliding occurs at a certain angle until it is completely closed. As an example, take the door 2 with a width of 595mm, a longitudinal wheelbase of 47mm, and a transverse wheelbase of 14mm. When the connecting rod length is 77mm and the initial angle is 14.5°, the displacement relationship is shown in Table 1. According to the distance that the door 2 panel of this refrigerator needs to exceed the door 2, the corresponding parameters are queried in the table. That is, when the critical safety distance of the door panel 9 exceeding the door 2 is 61mm, the door opening of 50° can be achieved, and the subsequent 40° door opening does not require relative sliding. According to the actual thickness of the door body and other parameters, the connecting rod parameters can be adjusted to reduce the door opening angle at which sliding stops.

[0068]

[0069] In another embodiment, in order to determine the critical safety distance, the first interference position and the second interference position on the door panel 9 where interference is most likely to occur can be determined first, and based on the fact that the first interference position and the second interference position never interfere with the accommodating space, the value range of the critical safety distance can be obtained.

[0070] See also Figures 4 to 6 According to the embodiment of the present application, the door panel 9 has a first interference position c and a second interference position d. The first interference position is located at the inner corner of the door opening side of the door panel 9, and the second interference position is located at the outer corner of the hinge side of the door panel 9. The "inside" and "outside" are relative to the refrigeration box 1. The side facing the refrigeration box 1 is the "inside" side, and the side facing away from the refrigeration box 1 is the "outside" side. Figure 4 is a top view, the first interference position and the second interference position are from Figure 4 It is a point in the middle. It can be understood that, for the door body assembly, the first interference position and the second interference position are respectively a vertical line. Among them, if the inner corner of the door opening side is in the shape of an arc, the first interference position at this time is the point on the arc segment farthest from the hinge axis 101 of the door 2. Similarly, if the outer corner of the hinge side of the door panel 9 is in the shape of an arc, the second interference position at this time is the point on the arc segment farthest from the hinge axis 101 of the door 2. Among them, the critical safety distance satisfies: before the first interference position leaves the accommodation space, there is a gap between the first interference position and the side wall corresponding to the accommodation space; when the second interference position leaves the accommodation space, there is a gap between the second interference position and the side wall corresponding to the accommodation space.

[0071] Combination Figures 4 to 6 When the box door 2 is closed, the distance between the end face of the door panel 9 on the opening side and the corresponding side wall of the accommodating space is δ1, and the distance between the end face of the door panel 9 on the hinge side and the corresponding side wall of the accommodating space is δ2.

[0072] δ1 is not less than the movement distance γ along the width direction of the accommodating space before the first interference position leaves the accommodating space, γ is also the vertical distance that the first interference position moves toward the side wall of the corresponding accommodating space. δ2 is not less than the movement distance λ along the width direction of the accommodating space before the second interference position leaves the accommodating space, λ is also the vertical distance that the second interference position moves toward the side wall of the corresponding accommodating space, that is, δ1≥γ, δ2≥λ. "Before the first interference position leaves the accommodating space" corresponds to the situation before the first interference position point c is flush with point e of the cabinet 6, that is, the situation where the interference position point c is located before the horizontal line where point e is located. "Before the second interference position leaves the accommodating space" corresponds to the situation before the second interference position point d is flush with point f of the cabinet 6, that is, the situation where the interference position point d is located before the horizontal line where point f is located.

[0073] Generally, it is required that δ1>γ and δ2>λ, although it is not excluded that in extreme cases δ1=γ and δ2=λ. When the door 2 is in the closed position, the width direction of the door 2 is consistent with the width direction of the accommodation space. As the door 2 is opened, the width direction of the door 2 and the width direction of the accommodation space form an angle.

[0074] According to an embodiment of the present application, assuming that the door panel 9 moves a distance Δs, the length of the side where point c and the hinge axis 101 (that is, point o) are located is set to a, and the angle between it and the horizontal line in the figure is set to α. At this time, the length of the side where point d and the hinge axis 101 (that is, point o) are located is set to b, and the angle between it and the horizontal line in the figure is set to β.

[0075] Figures 2 to 4In the figure, the position relationship (indicated by the dotted line in the figure) and the angle relationship of the refrigeration equipment (refrigerator) when the door is not initially opened and when the door 2 is opened to any angle are simplified and annotated. In the figure, the corners where interference may occur during the door opening process are marked with black dots, wherein the first interference position c is likely to interfere with the point e on the right side of the first cabinet panel 601, that is, point e is the critical point for point c to escape interference (leave the accommodation space) during the door opening and closing process, and the second interference position d is the corner point on the right side of the door panel 9, which is the corner point where the right end face of the door panel 9 first interferes with the left end face of the second cabinet panel 602 adjacent to the right side during the door opening and closing process. As can be seen from the figure, in the initial position, on the left side of the hinge axis 101, the angle between the hypotenuse oc between point c and the hinge axis 101 (point o) and the inner side of the door panel is θ0, and the angle when the door 2 is opened to any position is Δθ. At this position, the hypotenuse oc, the distance l2 and the distance l1 are represented by dotted lines; in the initial position, on the right side of the hinge axis 101, the hypotenuse between point d and the hinge axis 101 is od. When the door 2 is opened to any position with an angle of Δθ, the hypotenuse od, the distance l1+h and the distance l3 are represented by dotted lines; as can be seen from the figure, during the opening process of the door 2, if the door panel does not move along the door 2 toward the door opening side, as the opening angle increases, point d will soon interfere with the left end face of the second cabinet panel 602, resulting in the inability to open the door 2. Therefore, in order to avoid interference that affects the door opening, it is necessary to move the corresponding door panel 9 toward the door opening side by a distance Δs when the door opening angle is Δθ during the door opening process.

[0076] In one embodiment, δ1≥γ=a×cosα-l2.

[0077] in,

[0078] As described above, Δθ is the angle of rotation of the door 2 during the opening process, and Δs is the distance that the door panel 9 moves relative to the door opening side of the door 2 during the opening process.

[0079] In one embodiment, δ2≥λ=b*cosβ-l3.

[0081] Therefore, when l1, l2, l3, h, δ1 and δ2 are all determined, the value range of Δs can be obtained.

[0082] The above formula for calculating Δs does not constitute a limitation on Δs. For example, the above formula may also have a correction coefficient or correction parameter. In addition, the above formula is for the case where the hinge axis 101 is determined. If the door 2 is installed with a biaxial hinge or a movable hinge, the hinge axis 101 will change as the door 2 is opened, and the calculation formula for Δs will also change adaptively. The formula needs to calculate the moving distance of the hinge axis 101. In addition, if there is an installation gap between the door panel 9 and the door 2, then h in the above formula is the distance from the sliding surface of the door panel 9 to the outer surface of the door panel 9, and l1 is the distance from the hinge point of the door 2 to the sliding surface of the door panel 9.

[0083] Among them, δ1 and δ2 generally do not exceed 5 mm. For example, when δ1=δ2=4 mm, the value range of Δs can be obtained.

[0084] According to the embodiment of the present application, the critical door opening angle is between 1° and 105°. That is, when the door 2 is opened to the critical opening angle, the door panel 9 no longer slides relative to the door 2, thereby ensuring the stability of the door assembly structure and improving the user experience.

[0085] According to an embodiment of the present application, the maximum door opening angle is between 90° and 135°.

[0086] According to the embodiments of this application, see Figure 7 In addition to the sliding mechanism 4, a driven component 3 may be provided between the door panel 9 and the door 2 to ensure the smooth movement of the door panel 9. Figures 7 to 9 The driven assembly 3 includes a first track and a first moving part that can slide relative to the first track. Figure 7 The first track and the first moving part can adopt the structure of a slide rail and a slider. Figure 8 The first track can be in the form of a rack 406 in the sliding mechanism 4, and the first moving part can be a gear 407 meshed with the rack 406. The specific structural forms of the first track and the first moving part are not limited here, as long as the first moving part can move along the first track.

[0087] According to one embodiment of the present application, see Fig. 9The sliding mechanism 4 includes a base (not marked), the base is provided with a second track 401 and a third track 402; a second movable part 403 and a third movable part 404, the second movable part 403 can be slidably installed on the second track 401, the third movable part 404 can be slidably installed on the third track 402, and the third movable part 404 is connected to the door panel 9; the second movable part 403 and the third movable part 404 are connected at both ends of the connecting member, respectively, the traction mechanism drives the second movable part 403 to move along the second track 401, and the second movable part 403 drives the third movable part 404 to move along the third track 402 through the connecting member, and the moving directions of the second movable part 403 and the third movable part 404 are opposite.

[0088] According to an embodiment of the present application, the connecting member may be a flexible cable, such as a steel wire rope, or may be other components that can realize power transmission between the second movable part 403 and the third movable part 404. In addition, both the second track 401 and the third track 402 may adopt the structural form of a slide rail, and in this case, both the second movable part 403 and the third movable part 404 may adopt the structural form of a slider. Of course, the specific structural forms of the second track 401, the third track 402, the second movable part 403 and the third movable part 404 are not limited by the examples given here, as long as the second movable part 403 slides along the second track 401 and the third movable part 404 moves along the third track 402.

[0089] According to an embodiment of the present application, the connecting member may include a first flexible cable and a second flexible cable. The first flexible cable passes around one end of the base, and both ends are respectively connected to one end of the second moving part 403 and the third moving part 404; the second flexible cable passes around the other end of the base, and both ends are respectively connected to the other end of the second moving part 403 and the third moving part 404.

[0090] The specific structure of the sliding mechanism 4 is not limited to the example given here, as long as the traction mechanism drives the sliding mechanism 4 to move, the door panel 9 can be moved relative to the door 2. For example, the sliding mechanism 4 can be a structure of double slide rails and sliders mentioned above, or a structure in which a gear 407 and a rack 406 cooperate, etc. Figure 6 The sliding mechanism 4 includes a gear 407 and a rack 406, and the rack 406 is driven to move by rotating the driving gear 407, wherein the gear 407 is connected to the output shaft of the traction mechanism, and the rack 406 is fixedly connected to the door panel 9.

[0091] According to an embodiment of the present application, during the opening process of the door body assembly, the door panel is stationary relative to the door in advance before being rotated to the maximum door opening angle.

[0092] In one case, the movement of the door panel is controlled by a motor. For example, the motor drives the sliding mechanism to drive the door body to move relative to the box door. In this case, the purpose can be achieved by controlling the start and stop of the motor through the controller.

[0093] In another case, the movement of the door panel relative to the box door is driven by a mechanical structure, that is, by selecting a suitable sliding mechanism, the sliding mechanism can be ensured to have an engaged state and a disengaged state, and then in the engaged state, the door panel can move relative to the box door driven by the sliding mechanism; in the disengaged state, the door panel is stationary relative to the box door. Specifically, before the door panel movement distance Δs reaches the critical safety distance, the sliding mechanism is in the engaged state; after the door panel movement distance Δs reaches the critical safety distance, the sliding mechanism is in the disengaged state.

[0094] For example, see Fig.10 The traction mechanism includes an arc gear 504 and a motor. The arc gear 504 has a toothed portion; the second moving portion 403 is provided with a rack 406. In the engaged state, the rack 406 is meshed with the toothed portion, and in the disengaged state, the rack 406 and the arc gear 504 are separated; the motor power is coupled to the arc gear 504 to drive the arc gear 504 to rotate. Of course, in order to achieve the switching between the engaged state and the disengaged state, the specific type of the sliding mechanism 4 is not limited to the above examples.

[0095] According to an embodiment of the present application, an embedded refrigeration device is provided, including a refrigeration box body 1 and a door assembly, wherein the refrigeration box body 1 is suitable for being embedded in a receiving space, and the door assembly is installed on the refrigeration box body 1.

[0096] According to an embodiment of the present application, a method for controlling a door assembly of an embedded refrigeration device is provided, comprising:

[0097] Step 10: determining a critical safety distance of the door body assembly when rotating relative to the refrigeration box based on the size parameters of the door body assembly, wherein the refrigeration box of the refrigeration equipment is suitable for being embedded in the accommodating space formed by the mounting body, the box door of the door body assembly is suitable for being rotatably connected to the refrigeration box, the door panel of the door body assembly is movably mounted on the box door, and the door panel can move along the width direction of the box door, and the critical safety distance is the minimum sliding distance required for the door panel to not interfere with the outside world during the process of the box door rotating from the closed position to the maximum opening angle;

[0098] Step 20: During the process of opening the door, determine that the movement distance Δs of the door panel toward the door opening side reaches a critical safety distance, and control the door body to stop moving relative to the door.

[0099] It should be noted that the above steps 10 and 20 are only for the convenience of description and do not constitute a limitation on the chronological order.

[0100] In step 20, the door opening angle of the door body assembly may be determined, and the current moving distance Δs may be indirectly determined by the corresponding relationship between the door opening angle and the moving distance Δs. For example, when the door body assembly is opened, the motor controls the movement of the door panel at a uniform speed based on the door opening angle. At this time, the mapping relationship between the door opening angle and the moving distance Δs of the door panel may be obtained. Of course, the relationship between the door opening angle of the door body assembly and the moving distance Δs of the door panel may be a simple linear relationship or a nonlinear relationship, as long as the door panels do not interfere with each other during the door opening process. No further restrictions are made here. Of course, a sensor may also be provided to directly detect the moving distance Δs of the current door panel.

[0101] In addition, it should be noted that all the contents of the door body assembly of the embedded refrigeration device can be used to explain the control method of the door body assembly of the embedded refrigeration device, so the repeated contents will not be repeated.

[0102] Finally, it should be noted that the above embodiments are only used to illustrate the present invention, rather than to limit the present invention. Although the present invention is described in detail with reference to the embodiments, it should be understood by those skilled in the art that various combinations, modifications or equivalent substitutions of the technical solutions of the present invention do not depart from the spirit and scope of the technical solutions of the present invention, and should be included in the scope of the claims of the present invention.
